Embodiment 1
[0018] The solid adsorbent used in the present invention is to adopt Zn 2+ Ion-exchange modified Y-type molecular sieves for the adsorption and removal of oxygenates from mixed C4 hydrocarbons. In the experiment, dimethyl ether in a C4 hydrocarbon stream is used as a probe molecule to remove oxygen-containing impurities. The content of dimethyl ether was 150 ppmw based on the total weight of the supplied C4 hydrocarbon stream. The adsorption evaluation conditions are: at 2.0MPa, 35°C, 2h -1 The volumetric space velocity of the liquid is 2ml, and the loading capacity of the adsorbent is 2ml. The appearance of the adsorbent is a cylindrical particle with a particle diameter of 10-20 mesh.
[0019] Before the adsorbent is in contact with the C4 hydrocarbon material to be purified, it needs to be activated. The activation process and specific conditions are: the gas used for activation is CH with a water content lower than 10ppm 4 gas, first at room temperature 30°C under cons...
